SPECIFICATION forming part of Letters Patent No. 751,195, dated February2, 1904.

Application filed July 2, 1903. Serial No. 164,010- (No model.)

To all whom it may concern;

Be it known that 1, JAMES WV. NELsoN, a citizen of the United States,residing at the city of New York, borough of Brooklyn, county of Kings,State of New York, have invented certain new and useful Improvements inRiveting- Tools, of which the following is a specification.

This invention relates to improvements in riveting-tools, and especiallyto riveting-tools which are to be used for riveting the rail.- bonds ofelectric railways to the rails.

The object of my invention is to provide a new and improved rivetingtool which is simple in construction, can easily be conveyed from placeto place, readily applied to rails for riveting a bond-rivet through thebase-flange or web and does not contain any complicated machinery apt toget out of order.

In the accompanying drawings, in which like letters of referenceindicate like parts in both figures, Figure 1 is a vertical sectionalview through one construction of my improved riveting-tool as applied ona rail for upsetting a bond-rivet in the base of the rail. Fig. 2 is asimilar view showing the device as constructed and applied on a rail forupsetting a bond-rivet in the web of the rail.

The riveting-tool is provided with a metal frame or block A, adapted tohook on, clamp, or otherwise engage the head of the rail B. As shown inFig. 1, the frame A is provided with a hook adapted to engage therail-head at one side and underneath, the main body of the frame restingupon the head of the rail. That end of the frame opposite to the oneprovided with the hook is forked or otherwise shaped to form or supporta fulcral point for a pivoted anvil-lever C. This lever C, as shown inFig. 1, is pivoted by a pivot D in the forked portion E of the frame A,and the lever is so extended beyond the pivot D that its anvil part F isbeneath the base of the rail B.

In the frame A an opening G is formed which serves to guide a punch H,projecting both from the upper and lower end of this opening, andpreferably having a head H formed on its upper end. The rail is providedwith drilled or punched holes in its base for receiving the bond-rivetsJ, which are made of malleable metal, preferably copper,

and are attached to the bonds. These bondrivets are provided with a headand are inserted from the bottom through the openings in the base of therail, so that the upper ends of the shanks or stems of these rivetsproject from the upper surface of the rail-base. The frame A is hookedon the rail in the manner shown, the anvil F passing beneath the head ofthe rivet J. By exerting a downward pressure on the outer end of theanvil-lever the rivet is held securely in place by the anvil F, and thelower end of the punch H rests upon that end of the rivet projectingbeyond the upper surface of the base.

By means of a hammer or a pneumatic tool or any other suitable implementblows are delivered on the upper end of the punch H, whereby theprojecting upper end of the rivetstem is flattened out, so as to form ahead on the upper surface of the rail-base and whereby the rivet issecured firmly in the rail-base. The lower end of the punch can berecessed or shaped according to the desired shape of the head to beformed.

Vhen the rivet J is to be secured in the web of the rail, the frame A ismade substantially U-shaped and is so applied on the rail as to rest onthe head and against part of the under side of the head. The anvil-leverC is also pivoted to one end of the frame, and on the end of thisanvil-lever the anvil F is formed. The pivot D is so arranged inrelation to the anvil that the end of the anvil is at the side of theweb of the rail. That end of the frame A opposite the one to which theanvil-lever is pivoted is provided with a lateral extension G, in whichthe punch is guided to move horizontally toward the side of the web. Tosecure a bond-rivet in place,the rivet is inserted, and the frame isapplied in the manner shown in Fig. 2. The outer end of the anvil-leverC is pressed down, so as to press the anvil F against the head of therivet, the free end of the stem of the rivet projecting from theopposite side of the web. Then the free end of the rivet shank or stemis spread or upset or shaped into a head by delivering blows on thepunch in the manner pre-' viously described.

The above-described tool can be readily applied on a rail at the properplace, and by means of it the bond-rivet can be rapidly provided with ahead for securing it in place. Bond-rivets can be secured in the lateralflange of a rail in the same manner as in the base.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, 1s

1. In a riveting-tool, the combination with a frame shaped to engage arailway-rail or conductor-rail, of an anvil-lever pivoted to said frame,an anvil formed on one end of said lever and a punch mounted in saidframe movable toward the anvil,substantially as set forth.

2. In a riveting-machine, the combination with a frame shaped to rest onthe head of a railway-rail or conductor-rail and to engage the underside of said head, a lever pivoted to said frame, with one end extendingbeneath said frame, an anvil on said end of the lever, the frame beingprovided with a punch-guide and a punch mounted in said frame to movetoward and from the anvil, substantially as set forth.

In testimony whereof I have signed myname to this specification, in thepresence of two subscribing witnesses, this 30th day of June, 1903.

JAMES W. NELSON.
